Description
Technical field
The utility model belongs to oil field oil transporting appliance technical field, relates to a kind of crude oil that is used for and reduces the chemicals dosing plant that condensation point changes the crude oil low temperature flow, particularly a kind of dosing pour point depression device that is used to reduce condensation point of crude oil at course of conveying.
Background technology
Crude oil fluidity difference main cause: separate out the wax crystalline substance at low temperatures, these wax crystalline substances are tabular or needle-like mostly, be combined with each other and form three-dimensional mesh structure, and the oil content of low condensation point, greasy filth, colloid and asphalitine etc. are adsorbed on around it, or be enclosed in formation slack wax shape material in the net structure, and crude oil is lost flowability.The effect of pour point depressant for crude oil is to influence the growth course of the mesh structure of wax crystalline substance, thereby the freezing point (pour point) of crude oil is reduced.Pour-point depressant changes the form of wax crystalline substance.That is after the adding pour-point depressant, the cloud point of crude oil can not change, just the form of wax crystalline substance has become loose wax-crystal structure (Slack Wax), after applying certain shearing force, its mesh structure is easy to destroy, or do not form the mesh structure, thereby increased the flowability of crude oil, reach the effect that reduces condensation point of crude oil.
Summary of the invention
The purpose of this utility model provides a kind of dosing pour point depression device that is used to reduce condensation point of crude oil, and this device is used for adding pour-point depressant at crude oil pipeline and reaches the reduction condensation point of crude oil, improves the flowability of crude oil under low temperature condition.
The technical scheme that the utility model adopted is, a kind of dosing pour point depression device that is used to reduce condensation point of crude oil comprises grug feeding jar, and grug feeding jar is provided with base, and base has sewage draining exit, and the loam cake of grug feeding jar is provided with main dosing mouth and secondary dosing mouth; On cover agitator also be installed, the agitator arm of agitator puts in the grug feeding jar; An outlet of grug feeding jar lower end is communicated with content gauge, another outlet of grug feeding jar lower end is communicated with flow valve, flow valve is communicated with explosion-proof measuring pump, valve table, valve, pressure meter successively, wherein be provided with safety valve between the port of export of the entrance point of valve and flow valve, manometric outlet is connected with the dosing pipeline.
Dosing pour point depression device of the present utility model, its feature also is: secondary dosing mouth is shaped as funnel-form.
Pour-point depressant chemicals dosing plant of the present utility model in the crude oil in the special-purpose pour-point depressant adding pipeline, can reach the reduction condensation point of crude oil, thereby increase the crude oil low temperature flow, increase work efficiency, avoided adopting traditional mode of heating conveying crude oil, both wasted energy the problem that equipment investment is high again.
Description of drawings
Fig. 1 is the structural representation of the utility model dosing pour point depression device.
Among the figure, 1. grug feeding jar, 2. loam cake, 3. main dosing mouth, 4. secondary dosing mouth, 5. agitator, 6. content gauge, 7. flow valve, 8. explosion-proof measuring pump, 9. safety valve, 10. valve table, 11. valves, 12. the dosing pipeline, 13. pressure meters, 14. agitator arms, 15. bases, 16. sewage draining exits.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Referring to Fig. 1, the structure of the utility model dosing pour point depression device is, comprise a grug feeding jar 1, grug feeding jar 1 is provided with special-purpose base 15, and base 15 is provided with sewage draining exit 16, the loam cake 2 of grug feeding jar 1 is provided with main dosing mouth 3 and secondary dosing mouth 4, be used to inject diesel oil, organic solvent diluting stoste, the wherein main dosing mouth 3 main pour-point depressants that add, secondary dosing mouth 4 is mainly in order to add thinners such as diesel oil, organic solvent, be shaped as funnel-form and be convenient to operation, be easy to control dosage simultaneously; Agitator 5 also is installed on the loam cake 2, and the agitator arm 4 of agitator 5 puts in the grug feeding jar 1, is used for stirring evenly soup; An outlet in grug feeding jar 1 lower end is communicated with content gauge 6, another outlet in grug feeding jar 1 lower end is communicated with flow valve 7, flow valve 7 is communicated with explosion-proof measuring pump 8, valve table 10, valve 11, pressure meter 13 successively, wherein be provided with safety valve 9 between the port of export of the entrance point of valve 11 and flow valve 7, off-load decompression when the pressure before the assurance valve 11 is excessive, the outlet of pressure meter 13 is connected with dosing pipeline 12, and dosing pipeline 12 is connected with the oil pipeline line.The motor of explosion-proof measuring pump 8 is a fire-proof motor, and its motor blower fan is not allow with plastic cement to join the metal fan blade, the generation spark in order to avoid fan blade displacement rotation and rear end cap or back cover rub mutually.Valve table 10, pressure meter 13 are used for pressure, the data on flows of testing.
The course of work of dosing pour point depression device of the present utility model is, in grug feeding jar 1, add corresponding solvent by main dosing mouth 3 and secondary dosing mouth 4, starting agitator 5 stirs, open valve 11 then, start explosion-proof measuring pump 8 and begin the admixing medical solutions of annotating, admixing medical solutions comes out from the outlet of grug feeding jar 1 lower end, passes through flow valve 7, explosion-proof measuring pump 8, valve table 10, valve 11, pressure meter 13 successively, is connected in the oil pipeline line by dosing pipeline 12 and goes.If the pressure before the valve 11 is excessive, admixing medical solutions can carry out off-load from safety valve 9, has guaranteed the safety of pressure system.
Dosing pour point depression device of the present utility model influences wax crystal mesh purpose growth course by drug effect, destroys the crystalline solid of wax under the prerequisite that does not change cloud point, reduces the flowability that condensation point changes Crude Oil Transportation, and the saving cost cuts down the consumption of energy.
Dosing pour point depression device of the present utility model uses by the trial run in the oil field, produces a desired effect.From the oil pipeline situation: with pour-point depressant, it is mobile poor that the condensation point of crude oil height is separated out wax, causes the obstruction of oil pipeline.After adding medicament, crude oil flow recovers normal in the pipeline, also effectively reduces energy consumption simultaneously.
Dosing pour point depression apparatus structure compactness of the present utility model, rationally distributed, be convenient to transportation, use simple to operationly, the integrated degree height is safeguarded simple, save manpower greatly, the minimizing of overhauling number of times simultaneously not only brings economic benefit to the user, has also alleviated labour intensity and pressure.
